IMPROVEMENT IN WATER-WHEELS.

To ALL WHOM IT MAY CONCERN:

' Be it known that I, JOHN Y. LANFAIR, of Queensbury, in the county of Warren, 'and State of New York, have inventeda new and improved Water-Wheel; and I do hereby ,declare that the' following is a. full, clear, and exactvdescription thereof, which will enable those skilled inY the art to make and use the same, reference being had to the accompanying drawingsforming part of this specification.

This invention relates to a new and improved water-wheel, of that class which are placed on a vertical shaft, and work Awithin a scroll or curb. i

The wheel is `designedvto be submerged, and is constructed in such a manner that power isV obtained froml the water, both by impact and reaction. fr

In the accompanying sheet of drawings- Y Figure 1 is a vertical section of my invention, taken in the line :z: x, iig.2.

Figure 2, a horizontal section of the same, taken in the line y y, g.A 1.

Similar letters of reference indicate eorrespondingparts.

A represents the water-wheel, and,

C is a s'quare wooden base, in theunder side of which there is-acircular recess to receive the wheel.

D is a square top, between which and the hase, C, the curb E isrplaced, concentric with the wheel, the top and bottom edges of the eurbhbeing fitted-iu annular grooves a, made in the un'der and upper surfaces C D, as4 shown clearly in fig. 1, the curb' and top and bottom being secured together, so as 'to form, perfectly watertightjoint-s, the top, D, and bottom or base, C, being firmly secured, so as to clamp the curb, by means of rods F. The curb E is provided with a gate, G, through which water is admitted within the 'scroll or curb, and within the latter there Vare placed two curved throats, H II, the mouths of which are at opposite sides of the centre of the curb. i

A tube, H', is at the centre of the bottom or hase, C, said tubo extending up through the contre of D, and has a cross-piece, I, over it. l

This tube admits air to the wheel, and likewise prevents allleakage around the shaft.

The curved throats convey the water to the buckets J of the wheel, which buckets have the parts b In', the former, b, being much wider than b', and having such a position as:V to receive the percussiv'e force of the water at right angles with the direction of theriiow of the same, while thebottoms of 6, as well as the parts b of the buckets, have such an inclination as to receive a power from the water as it escapes from the wheel, by reaction.

The wheelris designed to be of cast iron, and it maybe submerged, so as to operate with a good result, the increased head obtained by submersion more than compensating for the power expended in forcing the water through the wheel.

I claim as new,- and desire to secure by Letters Pntent- 'lhe wheel A, constructed or cast with buckets J, having two parts, IJ b', arranged as show n in combination with the curved throats H I-I, all arranged substantially as and for thepurpose specified.
